Installation error plugin WebSphere Application Server V7 in eclipse Mars

Question

Because of cost saving necessities we are currently looking for a way to install the WAS7 developer tools in an eclipse Mars. We chose this version because of the dependency on JDK7. Currently we are still working with an IBM RAD 8.5 but want to switch the IDE. Because of current server dependencies in the different software projects we need to use WAS7. We know the server version is out of support but any possible server migration is not within our responsibilities nor are we involved in any decision-making process at the moment and is therefore not an option.

We obtained "some help" from IBM, but their information has not been able to help us install WAS7 developer tools in the chosen eclipse.

We are able to reach a software site that allows us to select the WAS7 developer tools for installation, but when advancing in the plugin installation process we get a fatal error.

So we are asking if there is still a way to install WAS7 developer tools in an eclipse:

• An update site that works for WAS7 developer tools
• An eclipse version that allows for WAS7 developer tools installation
• A simple guide to help us install the plugin in the eclipse, in case a workaround needs to be applied

Any help is very much appreciated!

The information provided to us by IBM:

• https://marketplace.eclipse.org/content/ibm-websphere-application-server-v85x-developer-tools
• https://developer.ibm.com/wasdev/docs/websphere-developer-tools-releases/
• https://developer.ibm.com/wasdev/downloads/#asset/tools-WebSphere_Developer_Tools_for_Eclipse_Mars
• https://developer.ibm.com/wasdev/downloads/#asset/tools-IBM_Liberty_Developer_Tools_for_Eclipse_Neon
• https://developer.ibm.com/wasdev/downloads/#asset/tools-IBM_WebSphere_Application_Server_V7.x__V8.0.x_Developer_Tools_for_Eclipse_Oxygen

All of these links lead to either an error or an incompatibility message (if you have prove of otherwise, please provide us details in the).

Our configuration:

• Update site: http://public.dhe.ibm.com/ibmdl/export/pub/software/websphere/wasdev/V8.5/
• Eclipse version: Mars.2 Release (4.5.2)

The fatal error message in the installation process (my appologies for the wrap up):

Answer 1

After some additional exploring I got a perfect match between an eclipse and a plugin:

• Download eclipse Mars
• Download Developer tools for Mars from IBM tools site

As far as I tested, it was the only combination of the most recent eclipse IDE with a Developer tool that did not give any warning (installation in Oxygen generated an installation warning).

If anyone else experienced the same problem and resolved the issue with this answer, it can be accepted as the solution.

Answer 2

One 'core' error in the install log is:

requires 'bundle org.eclipse.core.runtime [3.6.0,3.9.0)' 

This is saying that the org.eclipse.core.runtime plug-in is required with a version of at least 3.6.0 and less than 3.9.0. This restricts the possible versions of Eclipse to between Eclipse 3.6 and 3.8 (inclusive) or maybe Eclipse 4.2 (Juno). Nothing newer is going to meet this requirement.
